GVP Reference Summary
The forested Mahagnao volcano in central Leyte Island is also known as Kasiboi or Casiboi. The andesitic volcano contains a steep-walled forested summit crater open to the south. Thermal areas with fumaroles and mud pots occur on the flanks. Two lakes, Malagsom and Danao, are located on the S flank. The former is a crater lake that is acidic and green in color, and the latter is a freshwater lake with an irregular shoreline and hot springs on its southern side. No source or confirmation is known for the possible 1895 eruption listed by the Commission on Volcanology (1981).
